SU-IVR Shelter Blast Hatch (Outward opening)

SU-IVR shelter hatches are designed for >100 (1 bar) blast pressure according to existing technical norms for civil defence shelters. The hatch leaf is made from reinforced beams with cover plates. The doors can be upgraded with armour plates for splinter / ballistic protection and specal materials for fire resistance.

SU-IVR hatches have a multipoint locking system with levers, providing improved protection against blast wave pressure and equipped with rubber seal for gas tightness.
